As proposed by TopHats, here are a few tweaks to the strategies:
Removed -1 attack for Infantry (doesn't change now)
-1 defence to all units (was -2).
Master of Stealth:
-40 cost for Marines (was -30)
Added -10 cost for Tanks
Removed +1 attack and +1 defence for Tanks and Infantry
Added +1 HP for Tanks and Infantry
Translations for Great Combinator description had to be removed, since they've become incorrect.
